magic-angle twisted bilayer graphene

Caption:MIT physicists have found a new way to switch superconductivity on and off in magic-angle graphene. This figure shows a device with two graphene layers in the middle (in dark gray and in inset). The graphene layers are sandwiched in between boron nitride layers (in blue and purple). The angle and alignment of each layer enables the researchers to turn superconductivity on and off in graphene with a short electric pulse. Credits:Credit: Courtesy of the researchers.

The ability to switch superconductivity on and off is a big step towards neuromorphic computing
